This is an odd one. I'm not sure it's the right place to ask, but maybe there are some sound / dog experts who can chime in? (no pun intended)
We use two sounds on our website to indicate success and failure on a quiz. Those are very simple and short sounds.
Somehow one of our customers reported that her dog was whimpering and really upset with both of those sounds. He's normally fine with lots of other sounds that dogs are typically unhappy with including loud sounds, hoovers etc. She even said it happens when she uses headphones!
Other than muting, or replacing those sounds (and upsetting other dogs?), is there anything we can do to clean the sound or detect what specifically makes them upset this or other dogs?
